Ok, I guess these can be EXPORT_SYMBOL_GPL then, or you could
remove them entirely by evaluating them in the boot loader and
changing the device tree accordingly.

For device drivers, it's usually better to make decisions based
on the revision of the device they talk to, not the revision of
the entire SoC, since that requires knowledge of all SoCs that
contain each version of the hardware macro.
